Question

Miller-Urey experiment is associated with

• A. Chemical evolution
• B. Biological evolution
• C. Molecular phylogeny
• D. None of the above

Answer 1

The correct option is A Chemical evolution

One of the main concepts of the origin of life was that life originated from inorganic molecules. That is chemical evolution preceded biological evolution. Miller and Urey conducted an experiment in 1953 in this regards. They created a primitive earth like the atmosphere in the laboratory. The inorganic substrates reacted to produce organic molecules as the products. This proves that chemical evolution was an important process preceding biological evolution.
